Simple water distributor

Abstract

The invention discloses a simple water distributor. The water distributor comprises an outer protective support layer (1), a central grid layer (2) and an inner support layer (3), wherein the outer surface of the central grid layer (2) is covered with precision filter screens (4), the inner support layer is connected with a water distribution pipeline through threads, and the outer protective support layer is connected with the inner support layer through threads, and the central grid layer (2) is clamped between the inner support layer and the outer protective support layer. During installation, 2-3 drum filter screens cover the central grid layer, and are fixed by snap rings and pressed tightly by the outer protective support layer, and according to the water distributor, the central grid layer and the filter screens are protected through the inner support layer and the outer protective support layer, so that internal pressure and external pressure can be resisted by the central gridlayer during operation of the water distributor; at the same time, through the outer protective support layer of the water distributor, the direct friction force between the dacron filter screens andparticulate matter is reduced greatly, the service life of the filter screens is prolonged, and the number of replacement times of the filter screens is reduced.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a simple water distributor. Background technique [0002] Water distributors are widely used in water treatment structural units in the field of water treatment to isolate granular substances in water treatment equipment units, such as anion and cation resins, activated carbon, quartz sand and other granular materials. In water treatment structural units, such as multi-media filter, activated carbon filter, softening tower, yin bed, yang bed and mixed bed, the water distributor needs to be installed in a small space. With the use of the water distributor, fine particles are deposited on the surface of the filter screen and the threaded joints, resulting in frequent replacement and difficult disassembly of the water distributor. The external precision filter of the common water distributor is fixed on the surface of the water distributor by nylon cable ties. As a result, the filter...

AI Technical Summary

Problems solved by technology

The external precision filter of the common water distributor is fixed on the surface of the water distributor by nylon cable ties. As a result, the filter cannot withstand the internal pressure from the inside to the outside, and it is easy to be stretched during the positive flushing process of the water treatment equipment. Problems such as broken filter

In addition, the filter screen is completely exposed in the container with particulate matter, which increases the frequency of contact between the filter screen surface and the particulate matter, resulting in the filter screen being prone to leaks
